Treating Fever Blisters Naturally

Treating Fever Blisters Naturally


Fever blisters are small, fluid-filled blisters that appear on the outside of the mouth. Though they are prone to appear during a cold or flu outbreak, they can happen at any time. Fever blisters are caused by the herpes HSV-1 virus, and appear any time that the immune system is compromised enough to allow an outbreak. These outbreaks can be painful, and are also easily spread through contact with an active outbreak. However, there are a few natural remedies that may help relieve the pain and reduce the amount of time the fever blisters are contagious.


At the first sign of a fever blister, place an ice cube directly on the affected area. Leave it there for a few minutes at a time for 10 to 12 minutes. Repeat this process every hour for at least five hours. The cold will reduce the blood supply to the fever blister, and will also slow down its growing progress and ability to spread.

Tea Bags

Placing a tea bag directly on the sore may also help heal the fever blister. This is largely because of the tanic acid found in most teas. Tanic acid is a natural antiviral that will help to reduce the severity of a fever blister outbreak and help the affected area heal faster.

Vitamin B

Vitamin B is an important vitamin that helps the body heal. Vitamin B helps you by strengthening your body’s ability to make healthy red and white blood cells. When a fever blister outbreak occurs, it is these blood cells that fight the infection and help the blister to heal. A vitamin B deficiency may also help cause a fever-blister outbreak.

Acidophilus, found in many common yogurts, may also help to not only treat a fever blister, but prevent them from occurring. Acidophilus are live cultures that help to bolster the immune system. Be sure to look for yogurts that have not been heat treated, as this process kills the natural cultures.

What to Avoid

To keep your fever blister from getting worse, there are certain foods that you should avoid. Salt will certainly make your sore worse. Though salt may actually help the sore to heal by helping to sanitize the wound, the resulting pain can be unbearable. You should also avoid foods high in arganine, as they may raise your risks of further outbreaks. In fact, arganine actually fuels the reproduction and growth of the herpes virus that is causing the sores. Foods containing the highest amounts of arganine are crab, lobster, peanut flour, sesame seeds, spinach, turkey, and game meats such as deer and elk.
